Track Spec Roll Restrictor Bush Upgrade Kit [MK6 / MK7 Fiesta ST]

The mountune MK6 / MK7 Fiesta ST Track Spec Roll Restrictor Upgrade Bush Kit has been developed for enthusiasts looking to maximise drivetrain control during track use. (This is designed to replace the existing bushes on your current mountune Roll Restrictor) Manufactured from high-performance 92A polyurethane, the Track Spec bush significantly reduces engine movement under hard acceleration, aggressive gear changes and high load conditions. The increased stiffness also helps minimise wheel hop, making it particularly beneficial for vehicles with increased power output. Unlike conventional rubber bushes, the polyurethane construction maintains its performance over time without deteriorating, providing improved durability and a longer service life. Each kit is supplied with the required installation grease for straightforward fitment. Recommended for track use only
